The western blue groper is a species of wrasse native to coastal waters of southern Australia from the Houtman Abrolhos in Western Australia to west of Melbourne. Adults inhabit coastal and offshore reefs in depths to 100m. Juveniles prefer relatively sheltered waters, such as shallow inshore macroalgal-covered reefs and seagrass meadows.
Benthic carnivores, they are known to feed on small crabs, smaller crustaceans, sea urchins and molluscs, including abalone. They use their strong peg-like teeth to prise urchins and molluscs off rocks, and will also bite off pieces of algal mat to eat small crustaceans and other benthic invertebrates that live among the algae.
